:BATTERY MOUNTING.

Application led December This invention relates to improvements in mounting devices for secondary batteries, and more particularly to a device for mounting a storage battery in an aeroplane in such a manner that it will be maintained in an upright position through the action ot gravity without respect te the position of the plane..

An object ot the invention resides in providing a universal mounting device tor a secondary battery in order that the battery may be mounted in an aeroplane and maintained in an upright position so as to prevent the .electrolyte i'rom leaking out and the operation otl the battery interfered with.

It is a -further object ot this invention to provide a support vfor a secondary bat-- tery adapted to provide a universal mounting therefor in order that it may maintain an upright position under the action oi' gravity wit-hout respect to the position or' the structure to which the mounting is attached, and in addition to provide conductor connections between the several parts of the mounting in order that circuitconnections can be made with the battery and in which the certain connections have relatively rotatable parts to freely admit of the universal movement of the mounting :tor the battery.

This invention comprehends numerous other objects and advantages residing in the details of construction and assembly of the parts1 which are more particularly pointed i out in the following detailed description and in the claims directed to a preferred form ot' the invention, it being understood however, that various changes in the size, shape and relation et the parts-may be made without departing from the spirit and scope ot' the invention as hereinafter set forth.

box and the manner in which it is mounted in the rotatable bracket member.

Fig. 5 is a detail sectional view on an enlarged scale of the mounting for the battery bor: in the bracket member.

Fig. 6 is another detail sectional 4view of one leg of the bracket. member 'showing the structure for absorbing vibrations and preventing transmission thereof to the battery.

1 indicates the main supporting shatt which is mounted in the sides of the body ot the aeroplane 2, in any suitable manner such as indicated in Fig. 1 of the drawing, and which terms the main support for the battery in the aeroplane. A rotatable supporting or carrying bracket is indicated at 3 a bore therein receiving` the shaft 17 and provided with roller bearings 5 having free bearing engagement upon said shaft. This construction provides a free rotatable mounting for the carrying bracket 3 on the which is provided with a head 4: having shaft. 1, while thrust bearings 6 prevent endwise movement ot the supporting bracket on the shaft.

Suitable adjusting members 7 are threadedly mounted on the shaft 1 as illustrated clearly in Fig. 3 tor adjusting the present bearing 6 in order to take up wear and lost motion and thereby prevent relativeinovement of the head d on shaft 1 in an axial direction.

On opposite sides oi the head e of the support-ing bracket and beyond the adjusting members 7 for the thrust bearing, collars 8 are mounted on the shaft 1 and held in position by suitable setscrews 9; insulating sleeves 10 are mounted on these collars and receive contact bands 11 which are provided with suitable terminal posts 12 to receive cable terminals from suitable electrical apparatus mounted in the aeroplane. A pair ot resilient thrust members 13 have one end thereof mounted between insulating plates la and secured to the head 4 ot the supporting bracket member.

The opposite ends of these resilient brush members 13 entend in opposite directions from the head a' and have bearing engagement on the contact sieeves 11 so that an electric circuit may be established with the apparatus mounted on the supporting bracket 3 without interfering with the rotatable mounting ot the bracket on the shaft 17 the brushes will inove with the head 4 in rotation about the shaft and have constant bearing engagement on the sleeves 11. The resilient brush members 13 are provided with suitable terminal posts 15 tor receiving' wire connections 16 from other' terminals on the supporting bracket 3 which will be described.

As .shown in Fig. E2, two sets ot brush members 13 may be mounted on the head el olf the supporting bracket and connected to the Wires 16 in order to insure constantJ and efficient circuit connections with the Wires 1G and the sleeves 11.

r1`he supporting member 3 is formed with a cross arm 1T which is provided with a pair of laterally extending parallel legs 18 at the ends thereof, one oi said legs being detachably connected with the cross arm 1T through the overlapped joint 19 shown clearly in Fig. et, the purpose oi which will presently appear. Each oit the legs 18 is provided With guideivays 2U for slidably receiving the stub shaft bracket 21 carryingl the stub shaft 92 at one end thereof and retained in said guideivays by the retainer plate 23. One end ot each ot the stub shalt brackets 21 is formed with a laterally projecting head 2l on the opposite sides of which engage the coiled springs which are received within the enlarged portions ot the guideway Q0.

The adjustinlg;` screws 26 are manually operable to vary the compression ol? the spring and thereby control the inovenient ot the stub shaft supportin n,l brackets 2l iu the legs 1S. These stub shafts project inwardly in substantial axial relation and in the assembled relation of the parts as shown in Fig. et, the inner ends of these stub shafts are rotatably received by the socket members 2T mounted on the ends ot the battery boi; Q8 so that the battery contained Within saidv bei; will be rotatably supported on the stub shaft 22. y

These stub shafts 22 are threaded as indi-- cated at 29 and receive the adjusting collars 30 i'or the thrust bearings 31 which are adapted for adjustment to control the position ot the battery bor; on the stub sha'tt 22 and prevent endwise movement. thereof relative to said stub shai't. Fig. 5 clearly shows the structure o3t` the socket members 9T' and the adjusting members k30 and the manner in which the parts are co-related so that the adjustment ot the members 30 will control the position of the battery box on the stub shaft and prevent the endivise anovernent thereoi1 as Well as compensate for wear be tween the parts.

Metallic collars 32 are pressed onto each stub shaft 22 and have the annular Aflanges at one end thereof bearing against the carrying brackets 21 as clearly shown in Fig. rthese collars receive insulating sleeves 33 provided with annular flanges on the end adjacent the lnacltcts Si', against which are positioned the ends oit' the contact bands 3ft which are positioned on said insidating:r sieeves and are provided with terminal posts 'for receiving the ends ot the `wires lt from the terminal posts 15. lfhese wires lil are -euided by suitable eyes t' inmintcd on the retaining plates :'23 as clearly shown in .liligz flu ltesilient brush members El? have one end extended late ally and secured tu the ede'e ol the battery bor; 28 as shown at "u" in Fig.

"lhe brush rnenilers 3T are provided with terminal pests IDE) 'tor receiving' the wire connections titl from the ter ininals ot the battery in the battery boi'L 2b.

The battery l throujgh the circuit members di' rotatably supported on the stub shailt airaiuflzt endwise n'iovenient with respect to said stub sha'lt through the adjustment oit' the collars 30. rl`he cir cuit connections trom the terminals oli' the battery througjfh the wires stt) to the two bras e. 3T provide tor the transn'iission olf uy troni the brushes to the sleeves "m gj of) and the wires lli Without in any way inlerterinpl with the rotation ot the battery relative to the supporting bracket member fl. The rotatable mountinfr ol the bracket member il by' the head lon the shalt Il, which mountingn is at right angles with relation to the ro tatable 1iiountingol" the battery bott on the stub shalt, permits the increment ol the bat-- tory box shalft 1 While endivisc movement is prevented through lie adjustment ol' the thrust bearings 6.

lCircuit connections are nuule through the wires 1G, the brush members lb', arid the sleeves 11 lo wire connections with any suitable apparatus ufxounted in the aeroplane. 'lliis provides a universal mounting ilor the battery in the box :28 relative to the support ing` body 2Q ot the aeroplane or other vehicle so that the battery box may be n1aintained by the action oi gravity iu a vertical plane at all times without respect to the position ot' the body The advantage ot this iirvention tor supporting a storage battery .in an aeriuilane is readily apparent in vieu' ol. the disadvantage in directly mounting the battery in the body 2 which is normally movable through an are of 3G00 which in numerous positions will permit the escape ol.' the elem trolyte in the battery so that it i usually iinpracticable to use a storage battery in an .aeroplane This invention will permit the 'tree movement of the aeroplane7 the battery being maintained constantly in a vertical plane thereby preventing the inverting ot' said battery with the consequent damage SFI lid

i lill to the battery in the aeroplane and yet the circuit connections Will be constantly maiir tained with the apparatus in the aeroplane tor Which a supply oi current is desired through the relatively rotatable brush and sleeve connection ior each side of the circuit to the battery.

ln addition, the resilient mounting orn the stub sha'lft carrying brackets 2l will subst-an tially eliminate the transmission oit' vibrations and the shocks applied to the aeroplane body to the battery. lt will prevent the battery from jumping or throwing the electrolytes out oit the cells through the jarring and bumping caused during landing and take-o of the aeroplane.

rthe present invention therefore provides an etiicient mounting :tor a secondaryrv battery in an aeroplane or the like to permit the iree universal movement of the supporting elements for the battery about the battery and allow it to remain under the action ot gravity in a normally vertical plane.

Having thus described my invention, What claim as new is l. i universal mounting for secondaryT batteries, comprising a shaft adapted Jfor attachment to a support, a supporting` bracket rotatably mounted on'said shaft and having a pair or parallel legs thereon lying in a plane substantially at right angles to said shaft, rotatable bearing members mounted on the ends of said legs ibrreceivinga battery and rotatablyT supporting the saine in said bracket, and relatively rotatable circuit making connections on the bracket and slniift permitting i'ree rotation o'l the bracket on the sliatt and maintaining circuit connection with said battery and circuits on said support.
